75% of this student's test average is 75/100 * 76 = .75*76 = 57.


\n" ); document.write( "That means the student needs at least 23 points from the final. 57+23=80.
\n" ); document.write( "

25/100 * x (final test score) or .25x >= 23
\n" ); document.write( "x>=23/.25
\n" ); document.write( "x>=92
\n" ); document.write( "
